At least two attorneys who have been closely following the trials of officers charged in the custody death of a black man are questioning whether prosecutors should move forward with any more trials.

Lt. Brian Rice was acquitted by a judge Monday, the third straight acquittal in the death of Freddie Gray, who was injured in the back of a police van and died a week later. A fourth officer’s trial ended in a hung jury.

Warren Alperstein, a prominent lawyer in the city who has been observing the case, said prosecutors have exhausted their theories and need to question whether to move forward.

Warren Brown, an attorney who has been observing proceedings, said the state at this point is doing worse than just 0-and-4 because of all the other charges in the case.

Two of the six officers charged have not gone on trial yet.
